A truly great American has left us!
On a serious note, I'm old enough to remember when my mother would set up the trays in front of the TV in our rec room and we would eat Sunday dinner while watching the Ed Sullivan Show. That was actually a treat for us! I guess Mom felt "liberated" from setting up the dinner table and from washing dishes (we didn't have a dishwasher yet). Now it seems like eating at the dinner table is the exception rather than the rule.
Update (July 25, 10:39 AM): This from comedy writer Jim Barach: "Gerry Thomas, the man who invented the TV dinner has died. He had an open casket funeral. They just peeled back the foil cover."
